Kensington - Orbit Wireless Laser Trackball Mouse - Black

Minimize movement and maximize comfort with the Logitech ERGO M575S wireless trackball mouse. Thumb control lets you move the cursor without moving your arm, while the sculpted ergonomic design fully supports your hand and keeps your forearm in a more natural position. This wireless ergonomic mouse has been developed by Logi Ergo Lab experts, user-tested and certified by ergonomists to give you 25% less muscle strain in your forearm . The smooth and responsive thumb control can be used anywhere – and since it doesn’t need to be moved, the ERGO M575S is perfect for tight setups and busy desks.

The Kensington Orbit Wireless Trackball with Scroll Ring is a stationary pointing device that replaces mouse movement with fingertip control of a 40 millimeter ball, suiting designers, editors and analysts working at crowded desks or on ergonomic keyboard trays. Because the base stays planted, the wrist and forearm remain still while the fingers do the work, which appeals to users managing repetitive strain and to anyone with limited desk clearance. A scroll ring encircles the ball for one-handed vertical navigation through long documents, timelines, code files and web pages, a smoother motion than a notched wheel across page-length travel. Optical tracking reads the ball rather than the desk surface, and pointer resolution steps through 400, 800, 1200 and 1600 dpi so cursor speed can be matched to spreadsheet detail work or wide multi-monitor sweeps. Dual wireless connectivity offers both a 2.4 GHz receiver link and Bluetooth Low Energy, and traffic is protected with 128-bit AES encryption for corporate environments that enforce wireless policy requirements. The ambidextrous layout serves left and right handed users equally, and a detachable wrist rest attaches at the front edge for added support during long sessions. Free KensingtonWorks software assigns functions to the programmable buttons, saving shortcuts for applications such as photo editors and browsers. Finished in space gray, the trackball works with Windows and macOS computers and installs with no drivers required.
